If you would like to create a hash of your files to be compared to then use [http://sourceforge.net/project/showfiles.php?group_id=67079&package_id=65262&release_id=530163 md5deep] to create your hash and then compare your hash (generated by Crypto plugin) to the hash you generated using md5deep.

Introduction
Version: 1.1.
This plugin provides you cryptographic interface using CryptoAPI. Using this plugin you can get common cryptographic hashes like MD5, SHA1, MD2, MD4.
Plugin DLL size: 3 660 bytes (not packed), 2 886 bytes (upx packed)
How to use
String Hash
Crypto::HashData "MD5" "String to be hashed" Pop $0
Supported algorithms: MD5|SHA1|MD2|MD4
File Hash
Crypto::HashFile "MD5" "$WINDIR\notepad.exe" Pop $0
Supported algorithms: MD5|SHA1|MD2|MD4
If you would like to create a hash of your files to be compared to then use md5deep to create your hash and then compare your hash (generated by Crypto plugin) to the hash you generated using md5deep. For example I generated notepad md5 checksum by doing the following in the Windows Command Line:
md5deep.exe "C:\Windows\notepad.exe" > hash.txt
Then I opened hash.txt and it looked like
ff7f14fda901090e337488a1900e3660 C:\Windows\notepad.exe
So from there I was able to use Crypto to ensure that notepad hasn't changed:
Crypto::HashFile "MD5" "$WINDIR\notepad.exe" Pop $0 StrCmp $0 "ff7f14fda901090e337488a1900e3660" Continue MessageBox MB_OK|MB_TOPMOST|MB_SETFOREGROUND|MB_ICONSTOP "ERROR: notepad.exe has been changed!!!" Quit Continue:
